Issues with Yellow ink

(1/4) > >>

Denis Kolar:
Would someone know what this would mean : CB Yellow 4449

I have a gallon of yellow ink that has this written on the container. I bought a few gallons of old ink from my supplier that bought out all the ink from a big print shop that was switching brands. This one does not have any marks on the bucket except that written with marker.
It is really runny and gooey, it is terrible to print, will not play well with other colors when wet-on-wet, and it is REALLY hard to clean of the screen when I used clean-up card (it gets all over the place).

Luckily I had another yellow, but that one is a bit darker.

Its a Rutland product........ the CB stands for the color booster. Its been a while since I've used the Rutland products but I'm pretty sure the color boosters were designed to "punch up" old muddy colors and were not intended to be used straight out of the bucket. Which is probably why you are having issues with it. At any rate I would call Rutland in Pineville NC (Tony Chapman would be my first choice but he can be a little difficult to get a hold of)
and they will give you give you a more informed response.

You cant go wrong with your own advice here. You never know what someone has put in their inks. By the time you find out its going through the dryer and your like WTF or in your case the sh!t just didnt work to start out with. I would get your supplier to take it back.
